Abstract

The invention discloses an efficient purple sweet potato seedling growing method, and belongs to the technical field of purple sweet potato cultivation. The method comprises the following steps: (1) seed potato pretreatment: selecting seed potatoes, soaking the seed potatoes into liquid medicine, cutting the seed potatoes into tubers, and spraying a chemical; (2) seed potato tuber arrangement and seedling growing: planting, moistening in warm water, and preserving heat with a mulching film; (3) purple potato seedling management: spraying the chemical and cutting seedlings. According to the seedling growing method, the surfaces of the seed potato tubers are soaked into or smeared with the growth-promoting liquid medicine, so that the seed potatoes can sprout and emerge as quick as possible; a seed arrangement way that a longitudinal section faces downwards obliquely is adopted, so that the sprouting rate and the seedling rate of the seed potatoes are increased; warm water is sprayed repeatedly in a seedling growing process, so that the temperature and humidity of soil in a seedling bed are improved effectively; a fertilizer is applied repeatedly in an appropriate amount in the growing process of the seedlings, and ordered temperature control is realized in combination with the mulching film at the same time, so that continuous and proper fertilizer support and proper temperature and moisture are provided for the growth of the purple sweet potato seedlings, the emergence rate and emergence quality are improved greatly, the seedling steps are simple, power equipment does not need to be used for supplying heat and preserving heat, and the investment cost is low.

Description

technical field [0001] The invention relates to a method for efficiently raising seedlings of purple sweet potatoes, which belongs to the technical field of purple sweet potato cultivation. Background technique [0002] Purple sweet potato is rich in nutrients and has special health functions. It is rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. It is also rich in selenium and anthocyanins. The protein and amino acids are very easy to eat. It is digested and absorbed by the human body to meet the nutritional needs of the human body; rich in vitamins can improve human vision, etc., so the health care effect has attracted people's attention. In addition, purple sweet potatoes are delicious and have various eating methods. They can be processed into whole powder and snack foods. The demand is large, so the cultivation of purple sweet potato has high economic benefits. [0003] At present, purple sweet potato seedlings are mainly raised ...
